Hunkering down for a hurricane means staying indoors, hunkering down in your house’s designated safe room (the innermost room with the fewest windows, or better yet, without any windows), keeping all interior doors shut, losing power and eventually the food in your fridge and freezer from spoilage, and wind and flood damage.
Compared to all that, social distancing and sheltering in place, with working power, air conditioning, internet, running water, and being able to go outside (as long as we maintain distance) is a cakewalk.
